Aside from using Google Trends, Google News, Facebook Trends, and Twitter Trends, I'm also using Quora for research. I know some would say that everything on Quora is highly-opinionated. There are conversations on Quora that are backed by research. I find Quora helpful because it helps us (in my content writing business) in creating the plot of the story that we would like to tell in our article. It gives us an idea on what other people think about a certain topic. Thus, it helps us write with a conversational tone. I hope you'll find this helpful. Who else is using Quora as a resource?
